A presentation of the principles of the fluidized technique and a review of its development in the fields of petroleum refining, hydrocarbon synthesis, and coal gasification. Several advantages are evident: (1) The constant uniformity of temperature control obtainable; (2) the elimination of undesirable hot-spots in catalyzed reactions by the rapid mixing and turbulence of particles; (3) the achievement at high efficiency of high rates of heat transfer; (4) the high reaction rates obtainable because of the large surface available, the scrubbing action of gases in reducing protective layers, and the maintenance of deep reaction beds under uniform conditions; and (5) the convenient and cheap method of movement of large quantities of solids.
